It is one aim ofthe invention to provide a simple, strong,

rugged, construction of this'character, that can be easily andinexpensively manufactured, and quickly and easily assembled and set up.In suitable forms of embodiment,

such as hereinafter described, the invention allows articles offurniture tobe compactly packed for shipment, with their legs detached,and to be easily and quickly set up by the ultimate user, or by anyunskilled per-:

son.

In the drawing, Fig. I is a fragmentary side view of a table'embodyingthe invention in one simple andadvantageous form of construction, aportion of the tabletop and one leg being broken away to expose theattachment of the leg behind. r

Fig. II isa tilted or perspective inside view of the corner portion ofthe box frame of the table.

Fig. III is atilted or perspective view of the upper end of a table leg.r

Thev table here shown has a box frame 5 of sheet metal of channelsection, and a flat top 6 of any suitable thin but strong sheet materialsecured thereto. As shown in Fig. I, cross braces? of sheet metal,stiffened with semi-circularly embossed ribs 8, extend across the frame5 and aflord intermediate support for the table top 6. The ends of thesecross braces 7 are secured (welded) to the lower side of the upperflange of the channel frame flange 11 projecting inwardfrom about themid-line of one of its main'fianges 12, and

formed by folding the sheet metal of the flange12 back on itself at 13and then bending it inward at right angles at 14. The

.As shown inFig. II, the angle plate 21 has depending tabs or-lugs v24,24, projecting downward below the: lower flange of the box frame 5; Theends of the angle plate 23 project or extend to'either side beyond thever-f I i I V tical edges of the leg 10. 'When the leg 10 j I has beenproperly aifixed to the table top'by forcing its heads 22 up into thesockets 20 as i far as they will go, so vasto interlockand Wedge themsecurely and firmly, the ears 24 are bent inward and upward, around andagainst thelower edge of the leg-angle 23, so

as to secure the leg to theframe and prevent disengagement of its headsorears 22 from the box frame socket ears'20. This can be done veryeasily, either by a few blows ofa 9 hammer, or by means of suitablepliersor the like. 2 V 4 r j Owing to the wedging of the heads 22, 22 ofa leg .10 in the table-frame sockets 20, 20 in the the planes of theadjacent table sides, 00-

' ears.

which lie at right angles, very rigid attachment of the legs to thetable is produced. 7 This attachment is [securely maintainedagainstdisengagement or loosening by the forcible interlocking of thebent-uplugs 24. Having thus described my f invention, I claim: I

1. A leg attachment construction for metallic furniture comprising asheet metal boxframe having on adjacentsides at. its corner pairs ofupward-converging inward-oflset ears, a post'or leg structure havin onadjacent sides undercut heads for hooixing be hindsaid ears and wedgingbetween them,
